The 1978 Cork Senior Hurling Championship was the 90th staging of the Cork Senior Hurling Championship since its establishment by the Cork County Board in 1887. The championship began on 6 April 1978 and ended on 22 October 1978.
St. Finbarr's entered the championship as the defending champions, however, they were beaten by Glen Rovers in the semi-finals.
The final was played on 22 October 1978 at Páirc Uí Chaoimh in Cork, between Blackrock and Glen Rovers, in what was their first meeting in the final in two years. Blackrock won the match by 4–12 to 1–07 to claim their 27th championship title overall and a first title in three years.
Bandon's Pádraig Crowley was the championship's top scorer with 1-25.
Format change
= Overview
=Since its inception in 1887 the championship had been played on a straight knock-out basis. If any team was defeated at any stage it meant automatic elimination. This system was deemed the fairest as the county champions would always be the team who won all of their games. There were some problems with this system and a special committee was established to examine the standard of competing teams. At the County Convention on 5 February 1978, delegates voted by 143 to 93 in favour of changing the format of the championship.
= New format
=Section one
Section one comprised the five top-graded club teams. They met each other on a league basis.

The third team in the section qualified for the championship quarter-final.

Section two comprised the five remaining club teams. They also met each other on a league basis. The two teams to top the league table qualified for the championship quarter-finals.
